Boost Up(ブーストアップBūsuto Appu), or "boost-type" (ブースト系būsuto kei), is a sub-type of the increase-type supportive spells, developed with the help of Boost Devices. It strengthens the specific existing parameter of the target.

Barret Power(バレットパワーBaretto Pawā) increases the destructive power of the target's shooting spells. However, it does not help the attack penetrate field defenses like AMF. Cast on Teana Lanster in StrikerS (ep.3).
